Specification of Letters Patent.

Patented June 15, was.

To all whom it may concern Be it known that I. EUGENE L. PERRY, a citizen of the United States, and aresident of the city of New York, county of Kings, State of New York, have invented certain new and useful Improvements in Can-Body- Making Machines, of which the following is'a specification.

My invention relates to can body making machines.

The object of my inv ntion is to provide a machine for automatically, rapidly and cheaply making can bodies of'the kind having non-collapsible lock scams or seams of the kind wherein onemember of the joint is furnished with a reverse fold or look shoulder to hold the-two members of the joint, stiff and rigid, and prevent collapsing under external pressure although the seam is unsoldered, such can bodies being ordinarily made from decorated blanks unsuitable for soldering.

A further object of my invention is to provide a machine which will form the bodies of cans from elaborately colored or decorated,

blanks by interlocking the ends of said blank so as to form a perfect joint and also to bend the blank into the proper shape prior to the formation of the joint, all this to be done in three operations and without in any way scratching, injuring or marring the elaborate ornamentation of the blank;

These objects are accomplished by my invention one embodiment of'which is hereinafter described. I v

My invention comprises in co'ciperative combination a double or dovetail hook former or folder for forming a double hook or one with a reverse fold, or of a general dovetail shape, upon one end of the body blank; a hook former or-folder for forming a single or plain hook upon the opposite end of the body blank; clamps for the blank while being operated upon by the hook formers or folders; bendc'rs or shapers for preliminarily bending the end portions of the body blank adjacent to the hooks to facilitate the proper inter-engagement of the hooks when the blank is subsequently bent around the horn, a body fornier horn preferably an expansible and collapsible one or one having a movable segment to facilitate'the interengagement of the hooks and their snug interlocking; a movable clamp for clamping the middle portion of the body blank against the horn; formers for doubling or bending the blank about the horn, preferably rollers to prevent marring of the decorated body blank; sea. adar r folders or formers operating successively to bend first one free end of the blank about the horn, and then the other to cause the hooks at the ends thereof to properly interengage While the horn is collapsed and then snugly engage when the segments of the horn are expanded; a plunger or bumper for compressingthe seam against the horn and causing the secondary hook or reverse fold of the dovetail hook to snugly and properly abut against, lock and stiffen the other members of the seam; a body blank conveyor for feeding or movingor conveying the blank first in position to be operated upon by the hook formers, then advancing it into position to be operated upon by thepreliminary body blank benders or shapers, and then further advancing it to the horn and formers or folders which bend the blank around the horn; and a can body discharger operating after the hrn is again collapsed to deliver the former can from the horn of the machine. By'this cooperative combination of parts a plurality of blanks, in different stages of formation into the can body, are simultaneously operated upon, thus enabling the can bodies to be rapidly and cheaply manufactured with the required noneol'lapsible type'o'f lock seam and without marring or injuring the decoration of the-blanks from which the can bodies areformed, one blank being operated upon by the hook forming or folding devices while another is being operated upon by the bending or shaping devices and another is being operated upon by the body former horn and devices directly cooperating therewith.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and more particularly speclfied 1n the claims.

For a more particular description reference is to be had to the accompanying drawings. forming a part hereof, in which:

Figure 1 is a plan view of a machine pro? vided with my improvement; Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation of the same: Fig. 4 is an endelevation of the same, the end shown being that on the left of the operator when feedin the machine. Fig. 5 is a plan view'partial y in section taken on the line 55 of Fig. 4 looking in the direction of the arrows. Fig. 6 is a front elevation, partially in section, of a part of the machine. Fig. 6 is a detail view of a cam hereinafter to be described. Fig. 7 is a longitudinal vertical section of a portion of the machine. Fig. 8 is a central vertical longitudinal section of the machine. Fig. 9 is an enlarged plan view of one of the folders and 'a portion of the machine adjacent thereto. ig. 10 is a sectional view taken on the line 1()-10 of Fig. 9, looking in the direction of the arrows. Fig. 11 is a plan view of the folders shown in Figs. 9 and 10, but shown on a larger scale. Fig. 12 is I a front elevation of the structure shown in Fig. 1],, Fig. 13 is an end elevation of the structiire shown in Figs. 11 and 12, the view being taken at the left end. Fig. 14 is a sectional view taken on the line 1 1-1i of Fig. 13, looking in the direction of the arrows Fig. 15 is a section taken on the line 15-15 of Fig. 14, looking in the direction of the arrows. Fig. 16 is a sectional view taken on the line 1616 of Fig. 14, looking in the direction of the arrows. Fig. 17 is an enlarged perspective View of a portion of the folder shown in Figs. 11 to 15.

Throughout the various views of the drawings, similar reference characters desig nate similar parts.

The double or dovetail hook former or folding device which produces the double hook or one within reverse fold or secondary hook may be of any suitable construction adapted to perform this function. It, however, preferably has or comprises stationary dies, folders or members 52, 53, a vertically movable die or folder 72 and a horizontally movable die or folder -l-3, the same operating to first form a groove to in one end of the blank with parallel upright walls 0;, 120 and with an intermediate or connecting wall :0 preferably curved, as shown in Figs. 26 and 27, and then by a. secondary operation of these dies or folders to incline or converge the parallel walls at 1: and thus form a .double or dovetail hook, or one with a secondary hook or reverse fold w on this end of the body blank as shown in Figs. 28 and 29.

The hook former or folder which forms a plain hook 0 upon the opposite end of the body blank may be of any suitable kind or construction adapted to perform this function. It preferably, however, has or com prises a die or folder 9%, operating in conjunction with. a movable die or folder 100 as shown in Fig. 29.

The body blank headers or shapers which operate to bend the end portions of the blank adiacent to the hooks preferably into approximately the shape shown in Fig. 29 may be of any suitable kind or coustrurlion adapted to perform this function.
